1989 Ford Bronco Power Windows

First check your operating switch ( make sure it has power) then listen to hear if the window motor is working. If the motor is dead take apart the door panel and weather sheeting (plastic covering the interior of your door) and remove the motor being careful to not damage the regulator. It will probably be easier to remove the mounting screws by first using a small hole saw drill to open up the access to the screws. While this seems drastic it will make the removal and re-installation much easier. Simply install and test before you put it all back together. It should take you about an hour or so

good luck
